Abstract: The pulsator washing machine drives the flow of water in the bucket through the forward and reverse action of the pulsator, forming a certain regular water flow. The structure of the pulsator has a great influence on the strength of the water flow, so how to design a pulsator structure with outstanding performance has become a major priority of the pulsator washing products. Taking the powerful pulsator as the research object, the working principle, washing system and parameter setting of the pulsator were introduced, and the limited modeling and water flow simulation analysis of the pulsator were carried out by using Realflow simulation software, so that a pulsator structure with the best characteristics was obtained. The CFD method of water flow simulation can greatly reduce the invalid design and shorten the design cycle, so as to provide references to the water flow design of the pulsator type washing machine.
